Regular oil changes improve engine efficiency and fuel economy.

Oil Change Intervals:
Every 5,000-7,500 km for conventional oil.
Every 10,000-15,000 km for full synthetic oil.

Best Oil for Fuel Economy:
5W-30 o r 10W-30 synthetic oil is recommended for most Hilux models.
Avoid thick oil e.g., 20W-50, as it increases resistance and reduces efficiency.

Impact on Fuel Economy:
Fresh oil improves fuel efficiency by 2-3% by reducing engine friction.
